Results:92 patients (113 ears) were examined by PTHT, AI , 40 Hz AERP,ABR and DPOAE. It was found that organic deafness was confirmed on 98 ears (86.73%), of which exaggerated hearing loss was 38 ears; nonorganic deafness was confirmed on 13 ears (11.50%); stimulated deafness was 2 ears(1.77%). 98 organic deafness ears were diagnosed, of which conductive hearing loss was 25ears; sensorineural hearing loss was 29 ears, and mixed hearing loss was 44 ears.

结果： 92例患者113耳行纯音听阈测试、声导抗、40 Hz AERP、ABR与DPOAE检测，发现器质性聋98耳，占86.73%，其中夸大性聋者38耳，夸大程度＜20dBnHL6耳，20～40dBnHL27耳，＞40dBnHL5耳；非器质性聋13耳，占11.50%，诈聋2耳，占1.77%；98耳器质性听力损失者中，25耳为传导性耳聋，29耳为感音神经性耳聋，44耳为混合性耳聋。

In concordance with this suggestion, it has been shown that dendritic cells from mice that are resistant to infection with Listeria monocytogenes preferent

和谐这一建议，它已经表明，从小鼠树突状细胞的抗感染李斯特菌优先表达TLR9 ，连同树突状细胞的成熟标志CD40分子和CD86 ，并产生高水平的IL - 12的，而树突状细胞从易感小鼠强烈表示TLR2 ，-4 ，-5和-6 ，并产生大量的趋化蛋白-1 （刘等人。， 2002年）。

The above facts indicated that silicon accumulation in the rice leaf sheath inside, the leaf surface and the sclerenchymatous cell, played the physical barrier role, delayed the hypha of sheath blight expansion.5、Analysing the physiological and biochemical mechanism of the resistance to rice sheath blight improved by silicon application in several respects.(1) After being inoculated with R.solani, O2 and POD activities disordered, CAT activities obviously declined. O2 producingvelocity in 91SP\'s leaves and leaf sheaths of Si+ rice plants were lower than those of Siriceplants, MDA content in leaves and leaf sheaths of Si+ rice plants were lower thanthose of Si- rice plants significantly in three days after inoculating, SOD、POD、CATactivities in leaf sheaths of Si+ rice plants were higher than those of Si- rice plantssignificantly in one day after inoculating, SOD、POD、CAT activities in leaves ofSi-treatment were higher than those of Si- rice plants significantly in three days afterinoculating. O2 producing velocity and MDA content in Lemont\'s leaves and leafsheaths of Si+ rice plants were lower than those of Si- rice plants significantly afterinoculating, and SOD、POD、CAT activities of Si+ rice plants were higher than those ofSi- rice plants significantly.

说明硅在水稻叶鞘内侧、叶表和厚壁细胞积累，起到了物理屏障的作用，延缓了纹枯病菌的扩展。5、阐明了施硅增强水稻抗纹枯病的生理生化机制(1)接种纹枯病菌后，两个水稻品种91SP和Lemont的叶鞘和叶片超氧阴离子自由基O2性紊乱，CAT活性明显下降；抗病品种91SP叶鞘和叶片施硅处理的O2产生速率小于缺硅处理，叶鞘和叶片MDA含量在接种第3 d后显著低于缺硅处理，叶鞘SOD、POD、CAT活性在接种1 d后一直显著高于缺硅处理，叶片SOD、POD、CAT活性在接种3 d后显著高于缺硅处理；感病品种Lemont叶鞘和叶片施硅处理的O2产生速率、MDA含量始终显著小于缺硅处理，SOD、POD、CAT活性始终显著大于缺硅处理。

According to a series of reaction of powdery mildew to different host, it could be confirmed that the disease was caused by Sphaerotheca fuliginea. There were two races, race 1 and race 2France, of which race 2 France was the dominant one.

根据一系列甜瓜白粉病菌鉴别寄主的抗感反应，初步确定北京地区瓜类蔬菜白粉病由Sphaerotheca fuliginea所致，且存在两个生理小种，即小种1和2France，优势生理小种是小种2France。

At the fifth day after BTH, SA and SiO2 spraying, seedlings were inoculated with Sphaerotheca fuliginea, and disease indexes, leaf lignin and HRGP contents were determined for four times at alternate days.

以抗白粉病甜瓜品种'银帝'和感病品种'卡拉克赛'为材料，用BTH、SA和SiO2溶液分别预处理，5 d后接种白粉病菌并分4次调查处理植株的发病情况、测定叶片细胞壁中木质素和羟脯氨酸糖蛋白含量。

Postmenopausal women had lower aerobic capacity compared with premenopausal women and age-matched males, which may correlate with endothelial dysfunction, impaired functional sympatholysis, and insufficient muscular oxygenation. Exercise capacity is associated with cardiovascular risk factors, such as lipid profile, C-reactive protein, and body mass index.

与停经前女性或同龄男性相比，停经后女性的有氧耐力明显减少，运动时的血管内皮扩张反应与功能性抗交感反应下降，使周边血管在运动时扩张能力较差、肌肉血流与含氧量低，均是导致运动能力下降的因素。

The main results were listed as follows:(1) Col-0 ecotype and the mutants were inoculated by Bipolaris oryzae, we discovered Col-0 ecotype was resistant to the isolation and vaccinal area emerged no spot; the mutants represented resistant.

将水稻胡麻斑病菌接种到拟南芥野生型和突变体植株上，发现野生型Col-0对病菌表现抗病，接种的叶片上没有任何病斑；而突变体植株则表现出不同程度的抗感差异。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
